At this point you should install the source or at least the headers for your kernel. The linuxtv drivers probably need to build against your kernel source. I am not 100% sure on this requirement, but it seems like an easy enough step to take.

Download the build tree and build it. It will download compatibility patches for your kernel if available:

git clone git://linuxtv.org/media_build.git
cd media_build
./build.sh

Now that we've built all the latest linuxtv drivers install them (from the media_build folder):

MythDora: A non-programmer, Linux and MythTV newbie wrote the added details about MythDora 10. I got the driver to work using Kernel 2.6.27.38-170.2.113.fc10.x86_64, by installing Mercurial and kernel-devel (plus a few other guesses, documented in the Discussion tab). Other research suggested I needed ncurses and ncurses-devel, and gcc, but I'm not sure of those are really required. Hopefully someone comes along and corrects any errors and incorporates additional information in this main article, which I found most useful.
